The subject belongs to the Physical Chemistry module and is fundamentally related to the subjects of said module and is important to understand the contents of the Chemical Kinetics and Catalysis subject (2nd semester of 3rd year) and Physical Chemistry of Materials (1st semester of 4th course.
The study of statistical thermodynamics serves to establish a connection between thermodynamics, spectroscopy and quantum mechanics. In the first part of the subject an introduction to the basic concepts of statistical thermodynamics is made, it is explained how to approach the relevant thermodynamic phenomena in chemistry from a microscopic point of view and how to calculate different thermodynamic functions: free energy, enthalpy, entropy, heat capacity, equilibrium constants, etc.
In the second part of the subject, transport phenomena are introduced, starting from a statistical derivation of the Maxwell-Boltzmann velocity distribution function. Concepts such as diffusion and/or migration of molecules and ions are introduced from a statistical point of view.
The study of electric charge transport in the vicinity of the electrodes completes the overview of electrochemical systems whose properties are closely related to the transport mechanisms studied.
These contents are a starting point for the study of electrochemical kinetics that students will work on in the following semester in the subject Chemical Kinetics and Catalysis and Physical Chemistry of Materials, which includes a chapter dedicated to corrosion

A) Large-group lectures: Lectures presented by the teacher to introduce those aspects of each topic that are considered fundamental for comprehension and development of the proposed activities. The lecturer will explain the most representative examples from each lesson. Diring the lectures the teachers will use Power Point presentations as a script of the contents. This material must never be considered as class notes. Usually, these classes follow the content of the reference manual. Attendance is not mandatory but strongly advised and quite important to progressively acquire the knowledge and to periodically interact with the instructor. Non attendance to lectures will have negative repercusión in the expected outcomes from seminars and tutorials.
B) Interactive classes in small groups: These are theoretical/practical sessions in which applications of the theory, problems, and exercises are proposed and solved, either individually or in groups. Students are expected to participate actively in these classes by solving exercises in class and tackling problems assigned as review for each topic. Tasks that require grading as part of continuous assessment must be submitted through the Virtual Classroom. During these interactive sessions, individual tests (multiple-choice or other formats) may be administered as part of the subject’s continuous assessment. Attendance at these classes is mandatory. Students must bring one of the textbooks listed in this syllabus and one computer per workgroup in order to carry out the proposed activities.
C) Laboratory practical classes: In these classes, students acquire the skills typical of a chemistry laboratory and consolidate the knowledge gained in theoretical classes. Practical sessions will be carried out in groups of 2 or 3 students.
Each group will have a brief laboratory manual including objectives and general considerations. Each group must prepare the contents and methodology in detail, using the necessary bibliography and consulting with the teaching staff.
At the beginning of the laboratory sessions, students must explain to the instructor how they will carry out the experiment, and the instructor will correct and/or guide them so that they can complete it successfully.
Before the end of the laboratory sessions, each group will submit a summary sheet with the main results of each experiment. The lab guidelines specify what these sheets must include.
At the end of the practical sessions, a test will be conducted to assess the level of understanding achieved, and the grade obtained will be part of continuous assessment.
Attendance at laboratory classes is compulsory. Absences must be justified with documentation, and only exam- and health-related reasons, as well as those specifically covered by current university regulations, will be accepted. Missed practical sessions will be made up, if possible, in agreement with the instructor and within the scheduled timetable of the course.
IMPORTANT NOTICE: At the beginning of the course, repeating students must contact the course coordinator to be informed whether they need to repeat the practical sessions. It is the students’ responsibility to be aware of their situation regarding the repetition of practicals and the impact of the practical grade on the final assessment.
D) Small group tutorials: There will be two sessions. These classes involve supervised activities, clarifiying doubts on lectures and laboratory, solving problems and exercises, readings related to the course, … The teacher can require the submission of a given exercise or report in advance to the tutorial session. These activities will be announced in advance and scheduled in the calendar. Attendance to these tutorials is mandatory and participation in them will be assessed.
The evaluation will be based on two aspects:
• Continuous assessment: 40% (Activities proposed by the instructor in seminars and tutorials 40%; quizzes and tests 20% and laboratory practicals 40%)
• Final exam: 60%
Students who do not achieve at least 80% attendance in interactive classes (seminars and tutorials) will lose the right to combine continuous assessment with the final exam; therefore, their final grade will depend solely on the exam.
The continuous assessment grade will only be obtained through active participation in the activities that make up this assessment (class presentations, problem-solving, multiple-choice tests, submission of exercises, etc.), demonstrating that the required knowledge has been acquired.
The FINAL MARK (N) of the student will be the one corresponding to the weighting of the mark of the continuous evaluation (0.40 × N1) and of the exam (0.60 × N2) or to the mark obtained in the exam (N2) , always the one that is most favorable to the student:
N = max(0.40 × N1 + 0.60 × N2, N2)
The most favorable grade will always prevail.
The final exam may include theoretical questions and problems related to the subject matter included in the course syllabus, regardless of whether the material was covered in lectures, interactive sessions, or laboratory classes. The exam will be graded out of 10 points.
Exam questions will include basic concepts that all students must master in order to pass the course. A minimum grade of 4.0 in the exam is required for it to be combined with continuous assessment.
Assessment of laboratory work. The reports submitted during the practical sessions, as well as students’ attitude and responses to questions posed by the instructor, will be considered in awarding a PASS in laboratory work. A PASS grants the right to take the laboratory exam, whose grade will be included in continuous assessment, and the final exam. A FAIL in laboratory work results in failing the course.
In cases of fraudulent completion of exercises or tests, the provisions set out in the Academic Assessment Regulations and Grade Review Procedures will apply.
Students who have been granted an official exemption from class attendance by the Degree Committee, in accordance with attendance regulations, must complete the activities assigned by the instructor as part of continuous assessment and a comprehensive assessment test covering the entire course. The final grade will be calculated in the same way as for other students.
Competency assessment:
• Seminars: CG2, CG3, DG5, CE5, CE14, CE15, CE20, CE22, CE23, CE24, CE25, CT1, CT2, CT3, CT4
• Laboratory practicals: CG2, CG3, CE20, CE22, CT2
• Tutorials: CG2, CE5, CE15, CE25, CT2
• Exam: CG2, DG5, CE5, CE14, CE22, CE23, CE24, CT1, CT2, CT4
Repeat students
Repeat students will follow the same attendance requirements as first-time students, with the following exceptions:
– Students who have previously passed the laboratory practicals will retain that grade for one academic year. However, they must attend the remaining interactive classes (seminars and tutorials) under the same conditions as other students in order to maintain the right to take the course exam.
Important data that the student must know in order to pass the subject:
- In the resolution of exercises, both in the continuous evaluation and in the exam, serious failures in basic mathematical aspects will be penalized with a reduction in the grade.
- In the resolution of exercises, both in the continuous evaluation and in the exam, not indicating the units that accompany the results obtained will be penalized with a reduction in the grade.
Class hours = 55 h:
Big group lectures = 23 h
Small group interactive classes = 10 h
Laboratory = 20 h
Small group tutorials = 2 h
Student's personal work = 95 h:
Self-study = 46 h
Problem solving and other tasks = 24 h
Preparation of the tutorials assignments = 10 horas
Preparation of laboratory practicals = 15 horas
• It is advisable to attend the lectures:
- Listening to the teacher's explanations will shorten the time of study and will facilitate taking notes and organizing the content in order to get ready for the exam
- The Power Point presentations, available to all students through the virtual classroom, are not a reference manual, just notes that constitute a guide for the contents. In addition, the instructor can explain contents not explicitly included in the slides.
- The attendance facilitates interaction between teacher and student through more participatory classes.
- The student becomes more familiar with the specific vocabulary and with equations and exercises that appear on each of the units. Students who do not regularly attend classes have greater difficulty in understanding the exercises of seminars and tutorials.
• It is important to study the new matter every day
• After reading an item in the reference manual, it is useful to summarize the important points, identifying the basic equations that should be remembered and making sure to know both its meaning and the conditions for applicability.
• Problem solving is fundamental to learning in this field and indispensable for preparing the final exam. The point is not to solve problems mechanically but to understand the meaning of what is being done, why it is done according to a certain method and its scope.
• The preparation of the laboratory practices before entering the laboratory is essential. First, you should review the important theoretical concepts underlying each experiment and then you should read carefully the script of the practice, trying to understand the objectives and the methodology of the proposed experiment. Any doubts that may arise must be discussed with the teacher. It is possible that some practices were performed before seeing the theoretical aspects in class. In these cases, previous work is even more important.
It is also advisable to have passed the subjects of the modules of Mathematics, Physics and General Chemistry, as well as all the other subjects of the same module.
